"Recently many ingredients have been restricted in cosmetic products, among others: Cyclopentasiloxane (D5) and Cyclotetrasiloxane (D4). Both of them are silicones, and they are used to protect the skin and to retain moisture."
"Cyclopentasiloxane (D5) can also be harmful to the environment."
"What do the Manufacturers need to do?
Make sure that the raw materials supplier provides you with Cyclopentasiloxane (D5) with the highest purity (99%) and that it does not contain Cyclotetrasiloxane (D4)
As a precautionary measure – plan to reformulate rinse-off cosmetic products with Cyclopentasiloxane by decreasing the amount until up to 0,1%, or by replacing it with another type of silicone"
